Use artificial nests that discourage predation
A replicated study on a wetland site in Missouri, USA (Brakhage 1966), found that 2% of 268 Canada goose Branta canadensis clutches in artificial nest ‘tubs’ were predated in 1962-5, compared 32% of 106 clutches laid on the ground. Artificial nests consisted of ‘No. 2 round washtubs’ placed in trees, on fence posts or specially constructed stands and partially filled with sawdust and straw to allow geese to bury unattended eggs. Tubs were placed 1-20 m off the ground (height did not affect predation rate). Some nests were still considered useable after nine years.
